Choose a password manager that works on all your devices, supports multifactor authentication (MFA), and offers storage and recovery options you understand. Then protect its vault with a strong master passphrase, turn on MFA, and replace reused or weak account passwords with unique generated ones.
Why use a password manager?
A password manager stores your account credentials and can generate long, random passwords, so you do not have to memorize a different one for every service. Unique passwords also limit the damage if one site is breached: a stolen password cannot be reused to sign in to your other accounts. NIST explains this risk in its Digital Identity Guidelines, and CISA recommends using a manager to create and remember strong passwords.
The manager becomes a high-value account because its login protects the vault. NIST notes that a modern PC can attempt up to 100 billion password guesses per second in the specific context of offline guessing against stolen encrypted passwords; that is not a universal rate for every device or attack. NIST’s Ryan Galluzzo, who leads its Digital Identity Program, puts the practical implication plainly: “Since that login protects all your passwords, it’s important to choose a password manager that supports MFA to ensure that it is as secure as possible.” NIST’s password guidance was updated August 20, 2025.
How to choose the right password manager
There is no universally best storage model or manager for every user. Compare the features and tradeoffs that affect how you use your devices and how you would regain access if something goes wrong.

- ✅ PROTECT ONLINE ACCOUNTS – A password manager, two-factor security key, and secure communication token in one, OnlyKey can keep your accounts safe even if your computer or a website is compromised. OnlyKey is open source, verified, and trustworthy.
- ✅ UNIVERSALLY SUPPORTED – Works with all websites including Twitter, Facebook, GitHub, and Google. Onlykey supports multiple methods of two-factor authentication including FIDO2 / U2F, Yubico OTP, TOTP, Challenge-response.
- ✅ PORTABLE PROTECTION – Extremely durable, waterproof, and tamper resistant design allows you to take your OnlyKey with you everywhere.
- ✅ PIN PROTECTED – The PIN used to unlock OnlyKey is entered directly on it. This means that if this device is stolen, data remains secure, after 10 failed attempts to unlock all data is securely erased.
- ✅ EASY LOG IN –No need to remember multiple passwords because by plugging OnlyKey to your computer, it automatically inputs your username and password. It works with Windows, Mac OS, Linux, or Chromebook, just press a button to login securely!
| What to compare | What to check | Why it matters |
|---|---|---|
| Device and browser support | Apps and browser extensions for the computers, phones, tablets, and browsers you actually use. | CISA recommends checking compatibility across your devices. A manager you cannot use everywhere may make it harder to keep credentials current. |
| Password generation | Whether it can create long, random, unique passwords, and whether you can configure those settings. | CISA recommends configuring passwords for length, randomness, and uniqueness. |
| MFA | Whether the manager supports MFA and which methods it accepts. | MFA adds a layer to the login that opens your vault. The FTC favors authenticator apps or security keys over text or email codes when available. |
| Storage | Whether the manager syncs through a cloud service or keeps a database you maintain locally. | Cloud storage can make access across devices convenient; a local database involves more backup and device-maintenance work. |
| Recovery | What the product says happens if you forget the master passphrase or lose a device. | Recovery options affect both access and security. NIST warns that a recovery method that compromises the master secret can compromise the vault. |
| Portability | Whether and how you can export or move records, according to the candidate’s current documentation. | Export features are not established uniformly here; check the specific product’s current instructions before relying on them. |
Cloud storage or a local database?
CISA describes a tradeoff rather than a universal winner. Cloud-based storage can provide convenient access across multiple devices, but the data is sent over the internet and stored on a server outside your control. A locally maintained database can offer more direct control, but CISA says it is more vulnerable to user error: you must maintain it across devices and make regular backups. These are general considerations, not a guarantee about every current product’s design.
Choose based on the arrangement you can maintain reliably. If you choose a local database, plan a separate backup and keep it current; a copy on a single device will not help if that device is lost or fails. If you choose cloud storage, review the provider’s current explanation of its storage and recovery design rather than assuming all services work alike.

Set up the manager and secure the vault
- Check the fit before creating an account. Confirm support for your devices and browsers, available MFA methods, storage model, and recovery process. CISA recommends weighing compatibility and recovery, and NIST cautions that recovery can affect vault security.
- Create a strong master passphrase. Choose a long passphrase you can retain securely. NIST’s Digital Identity Guidelines FAQ recommends a long passphrase and MFA. Do not reuse an account password as the passphrase for the vault.
- Install the official apps and extensions. Get them through the manager’s official channels for the devices and browsers you use. Exact installation screens vary by product, so follow that product’s current instructions.
- Turn on MFA for the manager account. Use a supported method you can access reliably. The FTC says an authenticator app or security key is a stronger option than text or email codes when available. A physical security key is optional; verify the manager supports the key before buying one.
- Move important accounts first. Replace reused or weak passwords with unique, manager-generated passwords. Start with accounts whose compromise could expose other accounts or sensitive information, such as your email and financial services.
- Make a separate backup if you use a local database. Store it somewhere resilient to loss or failure of the device holding the working database, and keep the backup up to date. CISA identifies regular backups and per-device upkeep as responsibilities of local storage.
- Enable MFA on important accounts where offered. The FTC recommends stronger options such as an authenticator app or security key over text or email codes when those options are available.
Make the migration manageable
You do not have to replace every password in one sitting. Prioritize accounts where a reused password could unlock other services, then update the rest as you sign in or review your accounts. For each account, let the manager generate a distinct password and save it in the vault; avoid keeping old reused passwords active simply because the new system is not yet fully populated.
Keep access to the manager’s MFA method and any recovery information in mind as you switch devices. Follow the provider’s current recovery guidance, and for local storage, verify that the backup can be found when needed. Neither export nor recovery behavior is the same across all managers, so confirm those details for your chosen product.
